How to style mobile menu

[newcoder1010]

Hi, 

I have this code to make the mobile menu (3 bars) to green.

 .responsive-menus.responsified span.toggler {
    padding: 0;
    display: block;
    color: green;
    border-radius: 0;
    background: #fff;
    box-shadow: 0px 0px 0px #000;
    font-size: 3.35em;
    text-align: center;
    /* cursor: pointer; */
    margin: 0;
    outline: none;
    /* width: 100px; */
}

 

When I view the page in desktop and then make screen mobile size, I see the mobile menu is green. When I visit the page in mobile phone, bar is kind of black. I am not sure why my phone does not show the color green. How to overwrite to make sure mobile menu bars are green?

Thanks.
